Use Case
Surface insights buried in your files
PDFs, spreadsheets, slide decks, contracts — Stacklink reads them all and makes every page searchable and queryable.
Universal parsing
PDF, DOCX, PPTX, XLSX, CSV, Markdown, HTML — every file format your team uses, fully indexed and searchable.
Table extraction
Data locked in spreadsheets and PDF tables becomes queryable. Ask "What was Q3 revenue?" and get the number.
Image & diagram OCR
Text in screenshots, diagrams, and scanned documents gets extracted and indexed automatically.
“The most valuable knowledge in your company is trapped in documents nobody has time to read.”
Capabilities
How it works for document intelligence
Smart chunking
Documents are split into semantic chunks — not arbitrary page breaks. Questions map to the right section, not the right page.
Contract analysis
Ask "What are the termination clauses in our vendor contracts?" and get a consolidated view across all uploaded contracts.
Slide deck search
Find that one slide from last quarter's board deck without opening 40 presentations. Search by content, not filename.
Version tracking
When the same document exists in multiple versions, Stacklink identifies the latest and links to the history.
Bulk ingestion
Drop a folder of 500 PDFs and they're indexed within hours. No manual tagging, no metadata entry, no busywork.
Structured extraction
Pull structured data from unstructured docs — names, dates, amounts, clauses — into a queryable format.
Under the hood
Real files. Real compute. Nothing leaves the room.
01 · Isolation contract
Your data, in the room — never out the door.
The file mounts read-only into an ephemeral sandbox with no outbound network and no persistent disk. Only the answer returns. Raw rows never cross the perimeter.
- Outbound denied. The sandbox cannot reach the internet — even if asked.
- Scratch only. Disk tears down with the session; nothing persists.
02 · The compute receipt
Every session itemised, signed, and replayable.
Every session leaves a clean receipt — the stages that ran, the file it ran on, and who asked. Re-run the receipt and you get the same answer.

03 · What you can ask
Different file shapes, same conversational grammar.
The grammar is the same across file shapes. Tables answer with numbers and charts; documents answer with passages and citations; decks answer with the slide that contains the claim.
Tables
CSV · spreadsheet
- “How is logo churn trending this year?”
- “Top 10 accounts by net-new ARR last quarter.”
- “Plot revenue by region, monthly, since Jan.”
Documents
PDF · long-form
- “What changed in the supplier contract vs the prior version?”
- “List every payment-term clause and its page anchor.”
- “Summarise the auditor findings in three sentences.”
Decks
Slide · presentation
- “Pull every revenue figure from the board deck.”
- “Which slides cite a source older than 90 days?”
- “Compare the FY targets across the last four decks.”
